This was (I believe) the 3rd iteration of Maestro’s Fuzztone fuzz pedal. The first 2 used germanium transistors and AA batteries. This marked the changed to silicon transistors and a 9v battery. Originals had 2N3860 transistors, but 2N2222s or 2N3904s would probably work just fine. Couldn’t find any info on the diode, so socket and experiment. I also couldn’t find any demos of the 2 transistor version (there is also a 4 transistor version of the FZ-1B), so you’ll just have to make it to find out!
